Expert-crafted AI skill documents for building long-lasting Swift applications.
Design, test, and evolve applications using the same principles, libraries, and techniques we use every day at Point‑Free.
We celebrate 8 years of Point-Free with a live stream! We take our brand new “Point-Free Way” skill documents for a spin by building a Flashcards app powered by SQLiteData, and we give a sneak peek at “Composable Architecture 2.0,” a reimagining of our popular library.
We clean up our test suite and make use of the expectDifference helper, for precisely describing changes to state in an exhaustive fashion. We will then rapidly add test coverage using the forthcoming “Point-Free Way” skills documents. Finally, we will achieve the seemingly impossible by writing a test against iCloud sharing!
SQLiteData is incredibly test-friendly. We will show how to configure a test suite for your data layer, how to seed the database for testing, how to assert against this data as it changes, how to employ expectNoDifference for better debugging over Swift Testing’s #expect macro, and how to control the uuid() function used by SQLite.
We dissect some of the most important and interesting topics in Swift programming frequently, and deliver them straight to your inbox.
We cover both abstract ideas and practical concepts you can start using in your code base immediately.
Download a fully-functioning Swift playground from the video so you can experiment with the concepts discussed.
We transcribe each video by hand so you can search and reference easily. Click on a timestamp to jump directly to that point in the video.
SQLite is one of the most well-crafted, battle-tested, widely-deployed pieces of software in history, and it’s a great fit for apps with more complex persistence needs than user defaults or a JSON file. This collection serves as an introduction to the basics of SQLite, as well as an exploration into more advanced topics and techniques for integrating SQLite into your applications.
Architecture is a tough problem and there’s no shortage of articles, videos and open source projects attempting to solve the problem once and for all. In this collection we systematically develop an architecture from first principles, with an eye on building something that is composable, modular, testable, and more.
What are the best, modern practices for persisting your application’s state? We explore the topic by rebuilding Apple’s Reminders app from scratch using SQLite, the most widely deployed database in all software. We will dive into many of SQL’s most powerful features, such as foreign keys, triggers, common table expressions, and more.
If you have ever created a binding using the get:set: initializer, you may want to reconsider. Doing so can hurt SwiftUI’s ability to animate your view. Luckily there is a better way. You can leverage @dynamicMemberLookup and subscripts to derive new bindings in a way that allows SwiftUI to propertly track where the binding came from.
SwiftData is not capable of filtering and sorting by raw representable enum properties in models. Predicates and sort descriptors will compile just fine when referencing enum properties, but it will crash at runtime.
SwiftData is not capable of sorting by boolean properties in models. And if you try to trick SwiftData to allow it, you will encounter runtime crashes.
Just finished the mini-series on enum properties by @pointfreeco! They pointed out what’s missing from enums in Swift and used SwiftSyntax to generate code to add the missing parts. Thanks for your work @stephencelis and @mbrandonw! #pointfree
Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️
I bought the annual subscription and after I watched all videos and played with the sample code and libraries I can say it was the best money I spent in the last 12 months.
Their content pushes the boundary of my knowledge, and it's fun to watch!
tfw you are excited for a 4 hour train ride because you'll have time to watch the new @pointfreeco episode 🤓🏔🚂 #MathInTheAlps #typehype
I really love the dynamics of @pointfreeco. The dance of “this is super nice because…” “yes, BUT….”. they clearly show what’s good, what’s not so good and keep continuously improving.
The best thing, that happened to me for a while. @mbrandonw and @stephencelis really provide a lot of new information according to #ios development and #functionalprogramming. All info could be used in real production without boring academics.
Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series
Through videos you constantly introduce ideas and patterns only to later reformulate them into more general ideas. This is awesome and helped me understand a lot of programming concepts. Well done!
Our free plan includes 1 members only episode of your choice, access to 75 free episodes with transcripts and code samples, and weekly updates from our newsletter.
